I bought this one because of the price and it was a waste of eight bucks! The cheap brittle metal crumbles before you even get it installed. Don't bother with this brand, the quality is non-existent.

It's just a simple switch, what could go wrong? Made in China - says it all. It actually didn't work! How is that possible, you say? Because the bottom of the screw knob has to come in contact with the top plate in order to complete the connection. This unit was not manufactured properly. The bottom of the screw did not project below the plastic casting of the green knob. It was necessary to file away excessive plastic in order to maintain contact. A switch like this cannot be allowed to operate inconsistently. Depending on your particular vehicle, it will permanently damage your alternator tf it disconnects while the engine is running.

Extremely easy to install and it disconnects the battery with a slight twist of the dial. I highly recommend it for short term storage

If you have a car that sits for long periods of time without being started or driven, this beats having to remove the negative lead to preserve your battery charge. Also,great when working on electrical components. Easy to install and use.

I have switched the ECM on my jeep 3 times and it still acts up and stalls in traffic. I had to get out and pull the neg cable off and reset the computer each time, fumbling with wrenches. I installed this switch and now when it happens, which isn't very seldom, just enough to be annoying, I pop the hood, hit the switch and I'm good to go. The product works great and they shipped it quickly.
